Objectives

• This course aims to provide a solid introduction to the principles of air conditioning and refrigeration. The course will provide a basic understanding of the types of air conditioning systems, applications and operating principles including both refrigeration and chilled water systems as well as basic ventilation needs and equipment
• Participants will learn the requirements for safe installation, pressure testing, charging and leak testing of refrigeration systems using fluorinated gases.
• The course will cover both installation and commissioning with the final section considering the maintenance requirements for refrigeration and water-based systems, including scheduling, record-keeping and legislation.This course focuses on all aspects of system design, from initial site survey to completion.
